Not anything major, it seems.
I do know a few people/companies that have fought for censorship of their critics and whatnot, so I've been attempting to do a bit of self-teaching on methods of preventing this. Similar to lulzsec, but obviously complying with the more strict views of Anonymous. If anyone has a compilation on methods, a share would be greatly beneficial to this board.
